There’s a heightened sense among some voters in the battleground states that their choices really matter, and that they really can shape the future direction that their country takes. That’s the sense I’ve been getting from several interviews that I’ve conducted with voters in Ohio and Texas for a developing story.

One result of this is the birth and proliferation of cool new ideas on the virtual campaign trail.

The latest example is a web site by Furqan Nazeeri, an entrepreneur working just outside of Boston, Massachusetts. He’s created ObamaCycle, a new social networking site that enables the supporters of Illinois senator Barack Obama to re-cycle their campaign materials.

It might not sound like much, but apparently there’s a long backlog for these kinds of materials at the online stores, and there’s a great demand for them. Nazeeri used Ning — a free application on the web that enables communities to instantly create their own social networks.

Have you developed a cool application on the web to support your candidate? If so, please tell us about it in the comments section!
